Keira Knightley has revealed that Joe Wright's adaptation of Anna Karenina is set to be "a very different take" on the Russian classic.
The actress plays the title role in the film, which is set for release later this year.
Speaking in Los Angeles at the world premiere of her latest film, Seeking A Friend For The End Of The World, the actress admitted Anna Karenina was an ambitious project to tackle.
"It's absolutely not an easy book to adapt," she said. "But I think Tom Stoppard did an extraordinary job with the adaptation.
"It's a very different take on it, it's very theatrical, I'm very excited about it."
Keira, who has already worked with director Joe on Pride And Prejudice and Atonement, stars alongside Aaron Johnson, Jude Law and Matthew MacFadyen in the adaptation of Tolstoy's epic drama.
"I've seen the trailer and it looks great," the 27-year-old revealed. "So fingers crossed."
